hi all,
some of my radiators are hot some are cold,
yet the pipes feeding them are all hot,up to
the valves.the valves are open but it seems the hot water isnt going into the rads just
straight to the return. all working fine yesterday, and ive tried bleeding them today.
very very confused.

Insertion tube that takes flow of hot water to middle of rad from twin entry valve has fallen off if the water is going straight to the return

thanks mate, ive turned off the hot rads and only left on the three cold ones. they are warming up after 5mins. not sure if i should open the other 6 fully or try to ballance them.
as ive got double entry valves is it better to start with return fully open or
inlet fully open and slowly open return?
